Application filed October 9, 1911.

T0 all whom t may concern Be it known that I, CLAYTON L. KENYON, a citizen of the United States, residing at Tama, in the county of rllama and State of Iowa, have invented a certain new and useful Improvement in Pumps, of which the following is a specification.

My invention relates to that class of pumps in which the pump rod is outside thedischarge tube or pipe which leads'immediately to the spout. ln such pumps it is necessary to provide a packing or stuffing device at or near the point where the pump rod leaves the well tube, in order that water may ilow into said discharge tube with little or no leakage at said point.

It is the object of my invention to provide a plunger` and adjacent parts which are longitudinally adjustable with relation to the pump rod.

A further object is to provide a plunger for pumps of this sort which is composed of few and simple parts, inexpensive to make, and which may be quickly and easily assembled or taken apart.

More particularly it is my purpose to provide a cylinder above the point where the pump rod leaves the well tube, andto provide a sleeve on the pump rod within said cylinder, and disks and washers on said sleeve which parts are so constructed and arranged thatthe sleeve and thev disks and washers may be easily and readily removed from the pump rod for the purpose of repairing or replacing them.

A further object is to provide `means whereby the well tube and discharge tube may be adjusted longitudinally with reference to the pump stock.

My invention consists in certain details in the construction, arrangement and combination of the various parts of the device,

whereby the objects contemplated x are .at-

tained, as hereinafter more fully set forth,

Specification of Letters Patent.

Serial No. 653,591.

In the accompanying drawings, I have used the reference numeral 10 to indicate an ordinary pump stock to which is secured a handle 11. vEvtending downwardly from the pump stock is a pump rod 12. Below the pump stock and spaced apart from the same is the well tube 13, at the upper end of which is a cylinder 14 considerably larger in diameter than the well tube'13 and communicating therewith. EX'- tending upwardly from the cylinder 14 on one side thereof is a discharge tube or pipe 15 leading to the spout 16. Extending upwardly from the other side of the cylinder .14E is a tube or pipe 17 closed atits upper end and forming an air pressure chamber. The pump rod 12 passes centrally through the cylinder 14 into the welltube 13. EX- tcnding upwardly from the center of the cylinder 11 is a cylinder 18 which communicates with the cylinder 14 and is screw threaded at its lower end to t a screw threaded opening in said cylinder 14. The pump rod 12 is screw threaded over a considerable portion of its length near the upper and lower ends of the cylinder 18. Mounted on the screw threaded portion of the pump rod 12 near the' lower end of the cylinder 18 is a nut 19. Above the nut 19 is a washer 20. Mounted on the pump rod 12 above the washer 2O and designed to slide freely thereon, is a sleeve 21, the outer surface of which is provided with screw threads 22. Above the sleeve 21 on the rod f 12 is a washer 23, and mounted on the screw threaded portion of the rod 12 above the upper end of the cylinder 18 is a screw threaded nut 24. Mounted on the sleeve 21 within the cylinder 18 are disks 25 and 26, internally screw threaded to correspond with the screw threads on the sleeve 21. Between the disks 25 and 26 are one or more disks 27 which are mounted on the sleeve 21 and designed to slide freely thereon, and are not screw threaded. The lower portions of the disks 25,26 and 27 are of greater diameter than the upper portions thereof.

Mounted on the sleeve 21,v above the disks 25 and 27 are washers 28 of leather or other suitable material, the outer edges of which are bent downwardly so that these washers form valves with their outer edges resting between the upper portions of the disks and the inner wall of the cylinder 18. The pump stock is placed on a base or platform 30 preferably circular in form provided on each side of its center' with pairs of parallel upwardly extending flanges 31. Each member of each pair of flanges is curved outwardly from the other member near' its center so that circular openings are formed in the platform in which are received the pipes 15 and 17. The platform 30 is divided into three parts on the lines between the pairs of iianges. The outer flange on each side and the portion of the platform outside the outer flange forms a portion 32. The portions 32 and the main body of the platform 30 are secured together by means of bolts 3-1 extended through suitable openings in the flanges 31, and provided with nuts 33. By means of the detachable portions 32 of the platform 30, the pipes 15 and 17 may be adjusted longitudinally with reference to the stock 10.

1n the practical installation and use of my improven'ient in pumps, the well tube 13 is equipped with the cylinder 18 and the parts contained therein, and is secured to the pipes 15 and 17 and placed in the well. r1`he pump stock and the platform 30 are then secured to the well platform by means of bolts extending through the openings 35 in the platform 30, and the pipes 17 and 15 are adjusted in the platform 30. The upper and lower sections of the pump rod are screw threaded and are connected by the connecting device 36 which is provided with a lon- `.fitudinal screw threaded opening designed to receive the ends of the sections of the pump rod 12.

It will be seen that by means of the screw threads on the pump rod 12, the nuts 19 and 24, and the sleeve 21 may be adjusted lon'- gitudinally with relation to the pump rod 12. rlhe sections of the pump rod 1.2 may be disengaged by screwing the device 36 in either direction. The cylinder 18 may then be readily unscrewed from the cylinder 14 and removed from the pump rod. If desired the sleeve 21 may be removed from the pump rod without removing the cylinder 18, by removing the nut 211 after the device 36 has been removed from the lower section of the pump rod and by lifting the sleeve 21 out of the cylinder 18. The disks 25, 26 and 27 and the washer 28 may then be readily repaired or replaced. The sleeve 21 may then be replaced upon the lower section of the pump rod 12, the screw 2/1 secured in position, and the sections of the pump rod may then be connected by means of the device 36. lVhen it is desired to adjust the pipes 13, 15 and 17 longitudinally with relation to the pump stock 10, the nuts3G may be removed from the bolts 34 and the portions 32 detached. The pipes 15 and 17 may then be moved up or down as desired and are easily secured in any position of such movement by replacing the parts 32. Ordinarily in a pump of this kind considerable difficulty is experienced in making repairs when the stuffing box is found defective or leaking. By means of my adjustable sleeve 21, the disks 25, 26 and 27 and the washer 28, which are the parts most likely to cause trouble may be quickly and easily removed and repaired or replaced. The sleeve may be adjusted longitudinally for a reasonable distance on the rod 12, and the pipes 13, 15 and 1.7 are readily adjustable with relation to the pump stock.

1 claim as my invention:

In a device of the class` described, the combination of a pump stock, a multiple part pump rod operatively connected therewith, a cylindrical casing, spaced below said stock, an upwardly extending discharge pipe communicating therewith, a downwardly extending supply pipe communicating with said cylindrical casing, an upwardly extending tube above said casing, receiving a part of said pump rod, a sleeve adjustably mounted on said rod in said tube, and capable of being fixed in a variety of positions on said rod, packing devices adjustably mounted on said sleeve, means for detachably connecting the parts of said rod together adjacent to said sleeve.
